This reminds me of my video Is Fish Oil Just Snake Oil? (http://nutritionfacts.org/video/is-fish-oil-just-snake-oil/) Just like we thought omega 3 supplementation could help with mood, we also thought it could help with heart health, but the balance of evidence has decidedly shifted. I still recommend (file://localhost/My%20current%20recommendations%20are%20here/%20http/::nutritionfacts.org:2011:09:12:dr-gregers-2011-optimum-nutrition-recommendations:) the consumption of pollutant-free sources of preformed long-chain omega 3’s for cognitive health—I have a bunch of videos on their way explaining my rationale.

What about antidepressant drugs. Sometimes they can be absolutely life-saving. Other times they may actually do more harm than good. See my controversial video Do Antidepressant Drugs Really Work? (http://nutritionfacts.org/video/do-antidepressant-drugs-really-work/)
